IIRC when you use the "Subtitle and description" dupe detection method
and the subtitle field is missing for a particular programme, that
programme will not be regarded as a duplicate even if that exact
combination (no subtitle but desc present) has been seen and recorded
before. A subtitle must be present for this dupe method to work.

This is different to using the "Subtitle then description" method
which will ignore a missing subtitle and only use the description
field for dupe detection, but will prefer (and only use) a subtitle if
one is given.

I'm also unsure as to why your non-generic program IDs have not been
used in preference to the chosen dupe detection scheme. This behaviour
seems (to me) to be in conflict with the wiki article's description of
the use of the programid.

Anyhow, to fix this particular problem, follow Mike Holden's
suggestion and use "Subtitle then description" dupe detection method.
I use this for almost all scheduling rules (although I'm using a
different listings source to you which does not have as rich programid
information), and rarely have to manually intervene with the
scheduler's proposed recordings.

Cheers,
Nick
